Hi all,

I apologize if I am posting in the wrong section.

I have a very odd issue that I can not figure out with network adapters failing after joining machines to domain.

I have a Windows 2003 server. Joining Windows XP Pro works fine, but when I join (Windows XP Pro 64bit, Vista 32bit, Vista 64bit) to the domain their network adapters would fail. It would try to search for connection and never finds one. (This is both local area connection and wireless connection).

With Windows XP Pro 64bit I can get the network adapters to work with the steps below, but it would only work for a short while as it will fail again.

Is it something with my Group Policy? Where can I find out what policy controls the machines?

Also to add, before joining to my domain, the machines network works 100% fine, its only when I join the machine to the domain, and this is with IBM T400, T61p, T60.


Thanks all

1. What does it mean that network card fails? It shows up red cross? It doesn't repond? Explain this in details please.

2. As for GPO - you can check which GPO is applied by going into: start - run - cmd - gpresult

Also you can run rsop.msc to check if everything is applied properly.

Have you configured any GPO's in your AD?
By default there is only one - default domain policy and it shouldn't mess with your network cards.

What do you see in the faulty pc's logs?
